AI总结:

针对驾驶场景下EEG系统需兼顾意图理解与抗伪影的需求,提出掩码EEG建模框架预测驾驶意图,在困倦状态下准确率达85.19%,且通道缺失超半数时仍保持75%以上准确率。

摘要:

困倦状态下驾驶会显著提升车辆事故风险。尽管近期研究已聚焦于利用脑电图(EEG)检测困倦状态,以预防此类驾驶状态引发的事故,但驾驶场景下的无缝人机交互需要功能更全面的基于EEG的系统。该系统需具备理解驾驶员意图的能力,同时对突发动作引发的伪影具有鲁棒性。本文开辟了脑机接口(BCI)辅助驾驶领域的全新研究方向,研究与驾驶意图相关的神经模式,并提出一种驾驶意图预测新方法。具体而言,我们采用独立成分分析对EEG信号进行初步分析,结果表明驾驶操作意图与额中央区和顶叶区的神经活动密切相关。群体层面的功率谱密度分析也揭示,不同驾驶意图在频域存在显著差异。为利用这些脑动态特征,我们提出一种新型掩码EEG建模框架,用于预测人类驾驶意图,包括左转、右转和直行意图。我们在公开数据集上开展了包含全面定量与定性评估的大量实验,结果表明所提方法擅长在不同警觉状态下预测驾驶意图。具体来说,我们的模型在预测困倦受试者的驾驶意图时准确率达到85.19%,展现出其在减少与疲劳驾驶相关的交通事故方面的巨大潜力。值得注意的是,当超过一半的通道缺失或损坏时,我们的方法仍能保持75%以上的准确率,凸显了其在真实驾驶场景中的适应性。

英文摘要:

Driving under drowsy conditions significantly escalates the risk of vehicular accidents. Although recent efforts have focused on using electroencephalography to detect drowsiness, helping prevent accidents caused by driving in such states, seamless human-machine interaction in driving scenarios requires a more versatile EEG-based system. This system should be capable of understanding a driver's intention while demonstrating resilience to artifacts induced by sudden movements. This paper pioneers a novel research direction in BCI-assisted driving, studying the neural patterns related to driving intentions and presenting a novel method for driving intention prediction. In particular, our preliminary analysis of the EEG signal using independent component analysis suggests a close relation between the intention of driving maneuvers and the neural activities in central-frontal and parietal areas. Power spectral density analysis at a group level also reveals a notable distinction among various driving intentions in the frequency domain. To exploit these brain dynamics, we propose a novel Masked EEG Modeling framework for predicting human driving intentions, including the intention for left turning, right turning, and straight proceeding. Extensive experiments, encompassing comprehensive quantitative and qualitative assessments on public dataset, demonstrate the proposed method is proficient in predicting driving intentions across various vigilance states. Specifically, our model attains an accuracy of 85.19% when predicting driving intentions for drowsy subjects, which shows its promising potential for mitigating traffic accidents related to drowsy driving. Notably, our method maintains over 75% accuracy when more than half of the channels are missing or corrupted, underscoring its adaptability in real-life driving.
